Consider the three displacement vectors
Use the component method to determine (a) the magnitude and direction of the vector:
D= A+B+C and
(b) the magnitude and direction of:
The Attempt at a Solution
I did A+B+C which resulted in
2i-2j. I put them in the equation to find the magnitude which is
sqrt (2^2+(-2)^2) which resulted in 8. Square root of 8 is 2.82, but the back of the book says the answer is 4.47.
What am I doing wrong?
Thanks for any assistance!
